This is a wish list for upcomming development. all your requests are already in the pipeline. as for the no-screen bluetooth pairing:
Note: the Esp software does not work for this anymore, it is just for flashing now, and that has become redundant due to the flash from app option recently added. Personally I prefer Termite as a terminal (PC), and you can even use a phone with a terminal software and OTG connection, but it is important to set correct speed 921600 baud to get the correct output with bluetooth code.
(also, fixed bluetooth code is also a thing that is comming at some point)
